Hi all,

I've found myself doing something like the = following a lot in the past:

in= t i =3D 0, j;

And, naturally, I caught myself doing this recently:
=
auto i =3D 0, j;

About which the compiler complai= ned since, AFAICT, it is explicitly disallowed. I'm curious to know why. It= doesn't seem that much of a stretch to expect that j's type would be declt= ype(i)...

Thanks for any insight about this!
